Wash. Rev. Code § 81.53.070
At the conclusion of the hearing the commission shall make and file its written findings of fact concerning the matters inquired into in like manner as provided for findings of fact upon petition for new crossings. The commission shall also enter its order based upon said findings of fact, which shall specify whether the highway shall continue at grade or whether it shall be changed to cross over or under the railroad in its existing location or at some other point, and whether an over-crossing or under-crossing shall be established at the proposed location of any street or highway or at some other point, or whether the style and nature of construction of an existing crossing shall be changed, or whether said highway shall be closed and travel thereon diverted to another channel, or any other change that the commission may find advisable or necessary: PROVIDED, That in an emergency where a highway is relocated to avoid a grade crossing, or a new crossing is constructed in the vicinity of an existing crossing in the interest of public safety, the commission may order such existing crossing closed without notice or hearing as specified herein. In case the order made requires that private lands, property, or property rights be taken, damaged or injuriously affected, the right to take, damage or injuriously affect the same shall be acquired as hereinafter provided.
Any petition herein authorized may be filed by the commission on its own motion, and proceedings thereon shall be the same as herein provided for the hearing and determination of a petition filed by a railroad company.
